Alarms with manual reset:
the alarms with manual reset can be reset by pressing the
Manual defrost:
as well as the automatic defrost function, a manual defrost can be enabled, if the tempera-
ture conditions allow, by pressing the
HACCP function:
ir33+ is compliant with the HACCP standards in force since it allows the monitoring of the
temperature of the stored food.
"HA" alarm = exceeded maximum threshold: up to three HA events are saved (HA, HA1,
HA2) respectively from the more recent (HA) to the oldest (HA2) and a HAn signal that di-
splays the number of occurred HA events.
"HF" alarm = power failure lasting over a minute and exceeded AH maximum threshold:
up to three HF events are saved (HF, HF1, HF2) respectively from the more recent (HF) to the
oldest (HF2) and a HFn signal that displays the number of occurred HF events.
HA/HF alarm setting: AH parameter (high temp. threshold); Ad and Htd (Ad+Htd = HACCP
alarm activation delay).
Startup
Display of the details:
access to HA or HF parameters pressing the
glance over.
HACCP alarm erasing:
press the and buttons for more than 5 seconds, the message 'res' indicates that the
ON if RTC
alarm have been deleted. To cancel the saved alarms press the
present
more than 5 seconds.
Continuous cycle:
Pressing the buttons and simultaneously for more than 3 s enables the continuous
cycle function. During operation in continuous cycle, the compressor continues to operate
for the time 'cc' and it stops when reaches the 'cc' time out or the minimum temperature
envisaged (AL = minimum temperature alarm threshold).
Continuous cycle setting: "cc" parameter (continuous cycle duration): "cc" = 0 never acti-
ve; "c6" parameter (bypassing the alarm after the continuous cycle): "cc" = 0 never active; it
avoids or delays the low temperature alarm after the continuous cycle.
Procedure for setting the default parameter values
To set the default parameter values on the controller, proceed as follows:
1: switch the instrument off ;
2: switch the instrument back on, holding the
on the display.
Note: the default values are only set for the visible parameters (C and F). For further details
see table "Summary of operating parameters".
